The problem for these regions sustainable development cannot be negligible for its particularity innatural resources and environment. This paper mainly examines the issue about resource tax reform and the sustainabledevelopment of underdeveloped resource-rich regions. It first expatiates on regional characteristics of underdevelopedresource-rich regions, then analyzes the effect that resource tax has on the sustainable development of this type of regions,takes Yulin City as example to illuminate the negative influence on the sustainable development of those regions due to thedesign limitation of the existing resource tax, and put forward some suggestions, including to delegate tax legislativepower to lower levels, to increase resource tax rate, to expand its levied scope to give play to the potential main tax to localrevenue, to improve the design of resource tax, to enhance the its function of resource saving and environmentalprotection, to attach importance to regional interest of underdeveloped resource-rich regions and to improve of theinterest distribution system concerning the tax system and resource exploitation.展开更多

The comparison effect is the key issue of public good provision both in theoretical analysis and in practice. One major contribution of the paper is the extension of Clarke-Groves mechanism, to achieve which strategic behavior analysis is applied through the analysis and the comparison effect among various stakeholders in different stages is created and highly emphasized. In the first section of this paper, the definition of integrated water resources management (IWRM), the importance of stakeholder participation as well as some models and methods that have been applied are illustrated. Following this, the framework of analysis is elaborated, in which the scenario and aims are shown, and it is claimed that game theory is the main approach, which includes both cooperative games and non-cooperative games. To achieve the aims of the public project, five approaches from game theory are able to cover the entire process of the project, and the fourth approach on interest compensation mechanism is the highlight of the research. After this, the interest compensation mechanism is demonstrated in the model section, and is proved to be an incentive compatible mechanism that makes each stakeholder choose to behave in accordance with the interest of the entire project. The Clarke-Groves mechanism is applied and extended in establishing the model, and the utility change by the comparison among stakeholders (defined as the comparison effect) is involved. In the application section, a water project is analyzed in consideration of various stakeholders, and other possible applications are also indicated.展开更多

By applying data from 2000 to 2010 of 286 Chinese cities, this paper conducts an empirical analysis on the location of industrial enterprises of different time periods, regions and ownership systems. The results indicate that greater domestic market potential and international market demand are favorable to fostering or introduction of new enterprises. It also shows that coastal cities with better resource endowment are more attractive to corporate investment, while cities in interior regions have heavy and highly differentiated industrial tax burdens, which is unfavorable to the attraction of enterprises. In comparison, infrastructure and wage of cities have no obvious effect on enterprises' location choice. When it comes to enterprises of different ownership, domestic market potential and international market demand all have significant positive effects on the location distribution of foreign-funded enterprises, private enterprises and enterprises with investment from Hong Kong, Macao and Taiwan, while the level of urban industrial tax burden has an opposite effect. We find that the NEG model has a relatively strong explanatory power to the location of industrial enterprises in China.展开更多

E Method From the aspects of economic growth, development mode, environmental consciousness of national people, equity and efficiency, we analyzed the relationship between environmental tax and sustainable development in China, then studied the current taxation systems aiming at sustainable devel- opment. [ Result] In China, the design idea of present taxation system is not suitable for sustainable development, and a complete and scientific environmental tax system has not been established. Environmental tax indicates fairness principle, promotes equal competition and economic struc- ture adjustment, and enhances the environmental consciousness of national people. [ Conclusion] Environmental tax is not only an important sys- tem guarantee for the implementation of scientific development concept and circular economy, but also an effective method for governments to pro- tect environment and realize sustainable development.展开更多

Here, we build a computable general equilibrium model (CGE) comprising the functional equations of production, consumption, income/expenditure and resources to analyze the resource tax rate. The model uses the valorem tax levy to simulate the impact of economic and resource systems with different resource tax rates, by referencing the expected rate ranges of China and developed countries. The results show that the impact is different for social, economic and resources of varying degrees. In the relatively stable period of economic development, we can select a tax rate of 5% to 7%; during higher economic development we can select an optional high level of resource tax; and in a fluctuating economy we can choose a lower tax level.展开更多

It is necessary to levy a resource tax that reflects the real cost of coal resources. The results of our calculations show that from 1992 to 2009, the theoretical ad valorem coal tax rate determined in accordance with the user cost fluctuated between 2 and 14 percent. A further analysis of the impact of an ad valorem coal tax on the Chinese macroeconomy with a dynamic computable general equilibrium (CGE) model shows that a tax rate of 5-12 percent for coal resources would better reflect the cost of depletion of coal as a scarce resource, with the macroeconomic impact falling within the acceptable range. Therefore, resource tax reform is significant for China's sustainable development.展开更多

This paper studies how institutions in the host countries affect the location choices of China's ODI. Based on a deal-level sample from 2002-2011, this paper empirically tests how political institutions, political stability, government effectiveness, regulatory quality, rule of law and contrd of corruption in the host countries affect the location choices of China's ODI. On top of these institutional factors, we study the effects of tax evasion and natural resources in host countries, and their interactions with institutional factors. We find that political institutions in the host countries are not major concerns of the ODI, while government effectiveness, regulatory quality, and control of corruption have significant effects on the locations of ODI. In addition, China's ODI tends to avoid countries with strict legal systems. Tax evasion and resources are also major motives of China's ODI. General institutional quality and tax evasion are substitutes in China's ODI location decisions.展开更多

It is a matter of priority for hospitals to identify and enhance the basic organizational social structures which promote the development and maintenance of magnetism. A total of 436 valid self-administered questionnaires were collected from nurses. Paired sample t-tests, importance-performance gap analysis andANO-VAwere applied. The aims of this study were to investigate the key factors in and the gaps between nurses’ perceptions and hospital performance in areas contributing to magnetism. The results showed that Salary structure, welfare, and manpower deployment were the key forces of magnetism influencing nursing practice. Public and private hospitals showed significant differences in manpower deployment and nurse-patient relationships. Nurses who rotated shifts were more dissatisfied with their hospital scheduling system. Therefore, personnel policies and program are the primary forces in the development of a magnet hospital. Considering the demand for flexible scheduling of nurses, providing a supportive work environment, and keeping pace with today’s changing health care environment could achieve better outcomes for nurses, patients, and hospitals. These findings provide a reference to help set priorities for the implementation and development of effective strategies with limited resources. Public hospitals should take the lead in promoting magnet hospitals and set up reasonable salary systems, nursing workforce standards, and administrative support in order to attract and effectively retain nurses.展开更多

They follow the mud flat accretions which are unvegetated areas consisting of sand or gravel that are either exposed or flooded by tides. They provide 70% of the wood requirement along the Kenyan Coast. Currently, there are no harvest plans of the mangroves and there is selective removal of suitable poles and most of the quality poles have been wiped out. This not only leaves the inferior species unsuitable for the market but also affects the quality of the forest. Moreover, areas that are suitable for mangroves growth have been occupied by human settlement and infrastructure, hence, there is a need of sustainable use of the mangroves so as to protect them from degradating and eventually extinction. To achieve this, geospatial techniques need to be employed in order to determine the spatial extent of the vegetation and devise methods and plans of managing them. The Kilifi Mangrove Forest creek is home to major six species: Avicennia marina, Ceriops tagal, Sonneratia alba J., Rhizophora mucronata, Lumnitzera racemosa and Bruguiera gymnorrhiza. This study showed that the most dominant species in the forest is Avicenna Marina which had a percentage stand of 25.6%. The less dominant species Lumnitzera racemosa and Heritiera littoralis had a stand of 0.10% which were restricted for harvesting in the analysis, they need to be protected so as to prevent its extinction in the forest which will affect the biodiversity and richness of the forest. Density and heights of the mangroves were considered so as to decide on which areas to do reforestation in order to protect the forest and help in preventing soil erosion. The final suitable area for harvesting after carrying out conditional and majority filter was 394 acres which are 9% of the total forest area. The total area most suitable for reforestation is 1151 acres which are 27% of the total Kilifi Mangrove Forest. A recommendation for proper harvesting plans should be made by identifying suitable sites for harvesting and areas which showed low mangrove stand density should be identified and necessary measures should be taken to restore them.展开更多

The present work attempts to prioritize seventeen sub-watersheds in Ruparel watershed of Alwar district of Rajasthan, India. For prioritization of sub-watersheds, morphometric and land use/land cover (LULC) analysis were performed using remote sensing and GIS. Base map of the study area has been derived from SOI toposheet on 1:50,000 scale whereas LULC mapping was done using IRS P6 LISS III data. Standard methods for drainage morphometry have been followed for computing morphometric parameters such as linear and shape for seventeen sub-watersheds and allotted ranks based on their relationship with erodibility and a compound value has been calculated for final ranking. Five main LULC categories were computed and were assigned priority ranks and subsequently a compound parameter was determined for final ranking. Integration of both morphometric and LULC results reveal that SBW5, SBW7, SBW12 and SBW16 are the common sub-watersheds that fall under high priority, SBW3 falls under Medium category and SBW11 comes under low priority. The results of the analysis can be used to identify the sub-watersheds which need immediate restoration and will eventually help in watershed resource management for sustainable development.展开更多

A total of 436 valid self-administered questionnaires were collected from nurses. Paired sample t-tests, importance-performance gap analysis andANO-VAwere applied. The aims of this study were to investigate the key factors in and the gaps between nurses’ perceptions and hospital performance in areas contributing to magnetism. The results showed that Salary structure, welfare, and manpower deployment were the key forces of magnetism influencing nursing practice. Public and private hospitals showed significant differences in manpower deployment and nurse-patient relationships. Nurses who rotated shifts were more dissatisfied with their hospital scheduling system. Therefore, personnel policies and program are the primary forces in the development of a magnet hospital. Considering the demand for flexible scheduling of nurses, providing a supportive work environment, and keeping pace with today’s changing health care environment could achieve better outcomes for nurses, patients, and hospitals. These findings provide a reference to help set priorities for the implementation and development of effective strategies with limited resources. Public hospitals should take the lead in promoting magnet hospitals and set up reasonable salary systems, nursing workforce standards, and administrative support in order to attract and effectively retain nurses.
文摘Mangroves are salt-tolerable trees that grow on zones parallel to the coastline along the creeks. They follow the mud flat accretions which are unvegetated areas consisting of sand or gravel that are either exposed or flooded by tides. They provide 70% of the wood requirement along the Kenyan Coast. Currently, there are no harvest plans of the mangroves and there is selective removal of suitable poles and most of the quality poles have been wiped out. This not only leaves the inferior species unsuitable for the market but also affects the quality of the forest. Moreover, areas that are suitable for mangroves growth have been occupied by human settlement and infrastructure, hence, there is a need of sustainable use of the mangroves so as to protect them from degradating and eventually extinction. To achieve this, geospatial techniques need to be employed in order to determine the spatial extent of the vegetation and devise methods and plans of managing them. The Kilifi Mangrove Forest creek is home to major six species: Avicennia marina, Ceriops tagal, Sonneratia alba J., Rhizophora mucronata, Lumnitzera racemosa and Bruguiera gymnorrhiza. This study showed that the most dominant species in the forest is Avicenna Marina which had a percentage stand of 25.6%. The less dominant species Lumnitzera racemosa and Heritiera littoralis had a stand of 0.10% which were restricted for harvesting in the analysis, they need to be protected so as to prevent its extinction in the forest which will affect the biodiversity and richness of the forest. Density and heights of the mangroves were considered so as to decide on which areas to do reforestation in order to protect the forest and help in preventing soil erosion. The final suitable area for harvesting after carrying out conditional and majority filter was 394 acres which are 9% of the total forest area. The total area most suitable for reforestation is 1151 acres which are 27% of the total Kilifi Mangrove Forest. A recommendation for proper harvesting plans should be made by identifying suitable sites for harvesting and areas which showed low mangrove stand density should be identified and necessary measures should be taken to restore them.
文摘Watershed prioritization is considered as the most significant aspect in watershed resource management and development program. The present work attempts to prioritize seventeen sub-watersheds in Ruparel watershed of Alwar district of Rajasthan, India. For prioritization of sub-watersheds, morphometric and land use/land cover (LULC) analysis were performed using remote sensing and GIS. Base map of the study area has been derived from SOI toposheet on 1:50,000 scale whereas LULC mapping was done using IRS P6 LISS III data. Standard methods for drainage morphometry have been followed for computing morphometric parameters such as linear and shape for seventeen sub-watersheds and allotted ranks based on their relationship with erodibility and a compound value has been calculated for final ranking. Five main LULC categories were computed and were assigned priority ranks and subsequently a compound parameter was determined for final ranking. Integration of both morphometric and LULC results reveal that SBW5, SBW7, SBW12 and SBW16 are the common sub-watersheds that fall under high priority, SBW3 falls under Medium category and SBW11 comes under low priority. The results of the analysis can be used to identify the sub-watersheds which need immediate restoration and will eventually help in watershed resource management for sustainable development.
